Özet
In the current study, a series of pyrazole-sulfonamide derivatives (2-14) were synthesized, characterized, and the inhibition effects of the derivatives on human carbonic anhydrases (hCA I and hCA II) were investigated as in vitro. Structures of these sulfonamides were confirmed by FT-IR, H-1 NMR, C-13 NMR and LC-MS analysis. H-1 NMR and C-13 NMR revealed the tautomeric structures. hCA I and hCA II isozymes were purified from human erythrocytes and inhibitory effects of newly synthesized sulfonamides on esterase activities of these isoenzymes have been studied. The K-i values of compounds were 0.062-1.278 mu M for hCA I and 0.012-0.379 mu M for hCA II. The inhibition effects of 7 for hCA I and 4 for hCA II isozymes were almost in nanomolar concentration range. Published by Elsevier Ltd.
